Based upon your taste for female vocalist I would recommend Allison Weiss' album ...Was Right All Along. It's a little more on the melancholy Tegan & Sara side of the indie female vocalist genre and Allison Weiss actually does a Nineteen cover, but it definitely has it's ridiculously cheesy and upbeat acoustic moments too.

I'd recommend "Cosmogramma" by Flying Lotus since you listened to a lot of Hip Hop lately. Sometimes it might seem a little wonky and strange, but that's the charm of his work. For me his progressions were pretty mind blowing.http://vimeo.com/49443519here's the "trailer" for his new album.

okay, first off I feel like I'm walking up to someone who's talking about how they enjoy obscure acid jazz and saying "oh, jazz? you should listen to John Coltrane, he makes jazz!" but here goes:

I'm seeing a theme of acoustic guitar and well produced electronic music, mostly kind of ambient-y so I'm going to recomend Lemon Jelly's album Lemon Jelly.ky. it might not be entirely your cup of tea and you may have already heard of it but if you haven't heard it I would give it a try.
